' The present application is a division ofmy copending application Serial No. 236,281 filed October 21, 1938, now Patent No.'2, 2 14,7 79 issued September v, 1940. a p 7 One of the difllculties long experienced in, filling grease-guns with grease from original containers, such as drums or buckets, is that the lidfoifsuch grease drum or grease-bucket must. first be removed in. order, to get the greasegand the lid is frequently not replaced on the drum or bucket.

The grease-drums or grease-buckets are used: in

garages, farms and places where all of as:

c1811 matter, such as. leaves, dirt, grit and dirty water frequently get into the drum or bucketand on top of the grease. One customary way offrom which substantially all the grease may be completely removed so'that there is no waste of Aiurth'erobjectoi the present invention is to provide a grease container to which the generally cylindrical grease reservoir 01' the conventional grease guns may be screw-threadedly or otherwise detachably secured in a quick and easy manner, so

that by withdrawing the followerj piston in'said filling grease guns has been to submerge the end 'of the grease gun into, the drum or bucket of grease and pull the follower piston of the grease A gun follower piston back so as to 'suckthe'grase into the grease-gun as in Patent No. 1,377,423, This has a dual effect of-also carryingdirt into further effect of getting the greasegun reservoir One of the objects of-the present my grease reservoir of the conventional grease gun, said grease reservoirwill be completely filled with a 'freshsupplyof grease from thecontainer forming the'subiectmatter of the presentinvention.

With the above and other objects in view, the present invention consists of a generally upright cylindrical grease container formed of sheetmetal and capable oi containing a substantial quantity of-grease, as for instance, 10; 25, 50 or 100 pounds or more, and preferably having a freely floating piston-like follower plate therein adapted to rest on the top of the body of grease and to ride downwardly on the'top surface of the grease,

a socket on thetoutside of said container near the bottom thereof for receiving the intake end of the cylindrical grease reservoir of the conventional type grease gun, an'aperture in the bottom ofthe grease container and a'conduit'cornmunicating with said aperture and said'sock'et for conveying 'theegrease-drum or grease-'bucketland has -the.

that is, the type which may be carried about in the hand of the operator while in use, and more particularly, for use with the type of grease-gun (either manually actuated or pneumatically or electrically actuated) in which the generally cylindrical grease'reservoir of the grease-gun has within it a follower-piston and in which said cylindrical grease reservoir is refilled from time to time by unscrewing or otherwise detaching from said cylindrical grease reservoir "(containing said follower-piston) the high-pressure pump portion of the grease-gun (which is sometimes rehead or. high-pressure "head" then submerging thethns drawing the follower in said reservoirvby a suitable pull rod or chain so as to suck. said reservoir 023;.1,790,914; 1,894,274 and 1,926,398.

The grease-dispensing container of the present invention includes a generally cylindrical body 5 of suitable diameter and height to provide the desired volumetric capacity, and a bottom 0 having an opening 1 preferably centrally thereof. For that is, to accommodate ten or so pounds of grease, the convenient diameter is 9 inches, and a convenient height is 10 inches.

The entire container is formed of sheet metal, preferably suitable sheet steelsuch as is for steel drums, and of a suitable gauge according to the size of the container.

The bottom 6 is preferably formed with a flange 8 of suitableidepth to clear the lateral conduit fragmentary section on at the same time,

fragmentary view-of the a fragmentary. section drawn in aaoacoo l and socket in which will be described more fully hereinafter. The flange 8 is of an external diameter such as to telescope into the lower end of the cylindrical body 5 and is preferably drawn from the'same sheet of metal as that of which the bottom 6 is formed, as for instance by being a die or a suitable press, or by any other suitable drawing operation. The flange 8 is then turnedv and crimped along with the lower peripheral edge of the cylindrical body 5, to form a crimped and overlapping bead-like seam II, which unites the flange 8 with the corresponding lower portion of the cylindrical body 5, and which,

secures the bottom 5 permanently in place. The bottom 5 may also be held in place in a raised position by other means, as for instance by welding it in place to the side wall of the body 5 or by forming an outwardly pressed slight annular or peripheral groove in the body 5 at a suitable height at the lower extremity thereof into which the outer marginal portion of thebottom 5 may extend, to be held in place thereby. Likewise, the bottom 5 may have but a .short downwardly extending flange which may be a spot welded to the side of the body 5. The generally upright body 5 need not necessarily'be cylindrical in shape or circular in horizontal cross-section, but may also be polygonal inhorizontal cross-section, although the generally cylindrical form may be preferable. The portion of the body 5 which is bottom 6 ned not be continuous in its circumference, but may be cut out in parts to form a discontinuous lower extremity. Thus, for in- I, so'as to form a continuous but enclosed passageway,communicating with the interior of the to the'iiange I of the bottom.

I and extending Openings l2 and 8 and through container through theopening l'l are,extended through the flange the cylindrical body 5 of the container in regis- 1 tratio'n with the cross-section of the conduit 5, so as to form a passageway in continuation thereof. To the outside surface of the cylindrical body 5 of the container, the socket I0 is secured, also having a similar opening ll in the end wall 41 thereof inregistraion with the openings l2 and ll andin registration withthe conduit 9. The 1 socket in is provided with a generally cylindrical full of'grease. Grease-guns of this general type of conventionalgrease guns;

reinforcing ribs 2| may flange I! which isinternally screw-threaded as indicated-at ii, to receive the externally screwthreaded ends ll. of the cylindrical reservoirs it The end wall 41 of the socket III is made concave cylindrical curvature corresponding to the curvature of the cylindrical body 5 so that the socket I] fits s ly againstsaid body5. I

Within the cylindrical body 5 of the container of'thepresent invention, a freely floating pistonlike follower plate Iii is'provided in operative relation to the interior diameter of said cylindrical body 5;--said follower preferably having an upturned flange 20 of suitable axial depth to afford some guidance to the follower l9 so as to tend to prevent angularity or cocking. Radial be pressed into the follower so as to stiffen the follower plate 19. The ribs 2| are generally radial and decrease in height from the center towards the periphery as indicated in Figure 1. Three, four or more such below the l 1 with a generally radial ribs may ,be provided; -four being indicated in the drawing of Figure 1. Any suitable (conventional) handle may also be provided on the follower 19 for readily raising the follower out of the container-if it is desired tozrefill the containerafter it has been completely exhausted.

A lid 22 fitting loosely over more or less frictionally telescoped into the top or over the top of the body is also preferably provided for generally excluding dirt from. within the con tainer. The lid 22 is provided with a central .is secured beneath the opening I at one end raised portion 23 which is pressed in the. sheet\ metal and a screw 24 is threaded into a holefin the raised portion 23, so that by. removing or partly raising the-screw 24, a vent is provided at the top through which air may enterat the top of the container as grease is withdrawn from the bottom of the contalner,'so as always to maintain normal atmospheric pressure within the 7 container. The-upper periphery of the body 5 may also be suitably beaded or flared as indiportion39' of the rod 32 serves to turn the shutoflf disc 3|. This will serve-to prevent free drippage of grease when the device is not in use. If desired also, a screw-threaded cap 40 may also be provided to be screwed intoany of the sockets lilwhen'not in use. v In Figure 7,, alternative form of con'struc tion is shownin which'a thin weak leaf spring 4| thereof as at'point 42,:f'soa's to act as a weak spring'valve to minimize free drippage or drain-' age of grease when the device is not in use. The

spring 42 shown in the drawing of a comparative thickness greater than what it would normally have, but this is done merely ion purposes of illustration and for the greater convenience'in showing the spring in place.

In Figures 9 and 10, a semi-circular shut-ofl disc 43 is shown carried by and secured to a-pivot pin 44 having a slotted outerend 45 for receiving a screw-driver or any thin flatobject. The shutcated at 25, thereby to reinforce or stiflen the upper periphery of the container.

By raising the central portion of the lid 23, any rain or water which may tend to collect on the top of the lid is diverted from the vent opening at the top of the container so as to be excluded from the interior of the container.

"-in the gasket supporting member 29 so as to shut If desired, the bottom conduit 9, may be, 7

formed by pressing suitable channel-shaped depression 26 out of the bottom 5 of the device but integrally therewith, and then superimposing a flat plate 21 over said depression and support welding it, fusing it, soldering it, or otherwise securing it to the bottom 6 along the marginal zone around the depression 26; In this form of construction,-the flat plate 21 will contain the central opening I as indicated in- Figures 4, 5,

'7 and 8.

The socket in may either be of cast metal or it may be pressed sheet metal formed by the customary dieing operation. In Figures .4, 6, '7,

8 and 10, the socket is shown as being formed.

' of sheet metal, although, as stated, these sockets may-also be formed of cast metal."

Any of the sockets ID may be turned up at an angle as indicated in Figure 10, so that the cylindrical grea'se reservoir l8 of theconvena tional grease-gun may be applied thereto more conveniently by the operator, particularly in the case where the dispensing device of, the present invention maybe of a large size which would normally stand on the floor, although this upturned socket may also be used on smaller units.

The socket Ill may be applied to the cylindrical body 5 by means ofan annular eyelet 28 clamped porting member v 29. I meansof the screw-driver or any thin flat object,

oil disc is held in place by means of the pivot pin in any one of the forms of socket shown, as for instance by being fastened to the gasket sup- By turning the' disc by the disc 43 can bebrought over the opening 46 off the free flow of grease and can then again be turned away to permit the free flow.

Any of .the shut-off-means herein shown may be vused whenever grease of a more or less fluid scription .to indicate the scope of the invention.

thereby claimed as new and desired to be secured character is used or in climates where grease Having.thus described the invention, what is by-Letters Patent is:
